Answer:
Answer choice A) About 38.47 square units
Step-by-step explanation:
Since all four sides of a square have the same length, the perimeter of a square is just 4 times one of the side lengths. The perimeter of the square and therefore the circumference of the circle is 5.5*4=22. The circumference of a circle is 2 times the radius multiplied by pi. The radius of this circle is therefore:
Since the area of a circle is 
, the area of this circle is:

Since it is stated that the machine he bought only predict about 80%. Thus, about 20% are still possible that there are oils in the land that he owned.
In a 100% value = 80% were the 0 possibillites detected by the machine and 20% are still the possibility that it has an oil.
=> 80% = 0.80
=> 20% = 0.20
In the given choices. letter B has the closest value to the 20% that we expected.
Thus, let's have B as an answer.
Answer:
The answer is C. But I got 350.82
Step-by-step explanation:
The area for one triangle is 24 because A=h(height)b(base)timesb(base)/2. Both the triangles together would make 48 because 24+24=48
The are for one rectangle is 100.94 because A=b(base) times h(height). because there are 3 rectangles we multiply 100.94 times 3 which is 302.82
Then we add up all the areas 302.82+48 to get 350.82
Because this answer is slightly different I would assume it is C.
If my math is incorrect I apologize

Wait I just realized you have to convert it into square centimeters!
Answer:
The average is -49.
Step-by-step explanation:
You add all numbers and then divide by the numbers that your adding:
8+-67+-99+-91+-59+-81+46= -252
-252/7= -49
Answer:
i think it's the first option.
